AHF 005/010
■
Mechanical installation
The encapsulation of the filters has an IP 20
rating. The modules can be mounted side-by-side
with 2.36 in. (60mm) clearance.
To other components and to the cabinet walls, maintain
a horizontal clearance of at least 2.76 in. (70mm) and a
vertical clearance of at least 5.91 in. (150mm).
Only vertical installation is allowed (line
terminal at bottom).
For versions with bus bars (frame size
E - H), it is necessary to mount the
added covers to the connectors in order
to achieve the protection type IP 20.
■
Ventilation
The filters are cooled by means of air circulation.
Consequently, the air needs to be able to move freely
above and below the filter module. The efficiency
of the filter modules is greater than 0.98. When
installing a filter module in a panel or another enclosure,
ensure there is sufficient airflow through the enclosure
to limit heat rise in the enclosure.

NOTE
If other heat sources (e.g. Danfoss
adjustable frequency drives) are installed in
an enclosure with the harmonic filter AHF
0xx, this heat generation must also be considered
when calculating required airflow
NOTE
If the cooling air is polluted (dust, dirt swirl,
grease, aggressive gas), the function of
the filter module may be impeded. Ensure
sufficient countermeasures, e.g. separate cooling air,
mounting of air filters, periodical cleaning.
